  1. 26. NMR Studies of Bacterial Albumin-Binding Modules

    Författare :Maria U Johansson; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi; Physical chemistry; three-helix bundle; protein structure; protein PAB; protein-protein interactions; protein G; protein dynamics; NMR; module shuffling; GA module; evolution; albumin-binding; bacterial surface proteins;

    Sammanfattning : Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. LÄS MER

  4. 28. Molecular Structure in Liquid Crystals Studied by NMR

    Författare :Johan Thaning; Arnold Maliniak; Claudio Zannoni; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; Maximum Entropy; APME; Dipolar couplings; Liquid Crystals; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : This thesis is focused on structure determinations of molecules in liquid crystals using NMR. The systems described here exhibit orders ranging from nearly isotropic to essentially solid. LÄS MER

  5. 29. Charged colloids observed by electrophoretic and diffusion NMR

    Författare :Erik Thyboll Pettersson; Peter Stilbs; Terence Cosgrove; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; ENMR; electrophoretic NMR; dissusion NMR; electrophoretic mobility; double stimulated echo; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The thesis deals partly with methodology including construction of hardware and new pulse sequences in the field of electrophoretic NMR, and partly with practical use of ENMR and diffusion NMR in the investigation of charged colloidal systems. Several sources of artefacts are investigated, including gas production at the electrodes, electroosmosis and Joule heating effects that can cause convection. LÄS MER

  7. 30. Exploring the Molecular Behavior of Carbohydrates by NMR Spectroscopy : Shapes, motions and interactions

    Författare :Olof Engström; Göran Widmalm; Anthony S. Serianni; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; NMR relaxation; DNMR; CORCEMA-ST; carbohydrates; caffeine; O-antigen; glycofullerenes; organisk kemi; Organic Chemistry;

    Sammanfattning : Carbohydrates are essential biomolecules that decorate cell membranes and proteins in organisms. They are important both as structural elements and as identification markers. Many biological and pathogenic processes rely on the identification of carbohydrates by proteins, thereby making them attractive as molecular blueprints for drugs. LÄS MER
